Existance is four dimensional, stupid. Time is a dimension and is taken into consideration with physics. According to the new "String Theories" and "M Theory" there are 11 dimensions total, but we only know of 4 so the rest are a mystery. I have a feeling you still wont delete this YTMND even though its WRONG!!!

4 dimensions do exist, as do an infinite number. The problem? They are incomprehensible without loads of pot. Because loads of pot are illegal, so are 4 dimensional objects. Therefore, 4 dimensional objects exist--they're just been pushed underground.

According to string theory, the universe has many more spacial dimensions than just 3, they're just so small that you can't perceive them, like how if you look at very thin piece of string it looks 1 dimensional even though it's 3 dimensional like everything else. But then again String Theory has never been proven in any experiments so you're right for whats proven for the time being.

Just as the 4th dimension is time, the 5th dimension is choice, I didn't really understand the 6-9th dimensions, but the 10th dimension is everything, it is once every possible thing has been accounted for.

es joshin. Oh and does M theory support the existance of 4D objects? I know it involves 11 dimensional vectors but i wasnt sure about objects. Just because the dimension exists doesnt mean objects will have it.

To the high-and-mighty people saying the 4th dimension is time, that is a misinterpretation of dimensions. Any time you create an orthagonal projection accross other dimensions you create a new one. While space and time can be construed to be perpendicular, there's no inherent quality making time the 4th dimension.

To everyone who said that everything is 4 dimensional: Wrong 4th dimension, morons. There's the temporal and the spatial, the latter of which is impossible in our universe (disregarding the not-yet-proven string theories). Therefore, a 4 dimensional object is impossible (since 3d objects don't "travel" through/with time, per se, it flows around them, and that is why things change over time instead of staying the same [Anyway, that's what I think, and I'm sticking to it])

who's to say time isn't spacial. It's a means of interconnecting two different instances of the 3 dimensions below it. just like the 2nd dimension inter-links seperate 1st dimension. but instead of distance it's measured by duration.

And no one has any scientific knowledge whatsoever...For christ's sake, the 4th dimension isn't f*cking time. Stop listening to the bullsh*t people on the comment pages say and actually research your sh*t. There are 11 dimensions, with the 11th being a multiverse containing our infinate number of universes. We can't see past a 3 dimensional plane, therefore anthing past 3 dimensions seems uncomprehensible...but it is there.

How do you know, that what you know, is all there is to know about that which you know. Just because you cant percieve a fourth spatial dimension doesnt mean it doesnt exsist. For example, someone who was blind from birth, doesnt know what light it, has never seen it, cant even possibly imagine what its like. Yet it exsists.

you should have used a picture of HUDF-JD2 instead. It's a galaxy that's so massive, it should not be able to exist, according to current physics theories. I learned that from smoothmedia's site, a tiny glimpse.
